A0.2-m-long and 25-mm-thick vertical plate (k = 15 w/m-k) separates the hot water from the cold wa- ter. the plate surface exposed to the hot water has a tempera- ture of 100°c, and the temperature of the cold water is 7°c. determine the temperature of the plate surface exposed to the cold water (ts). hint: the t. has to be found iteratively. start the iteration process with an initial guess of 53.5°c for the ts, c

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

The sum of the normal stresses does not change as the stress state rotates through an angle. a)-trune b)- false
